Abstract
Description
- The present invention pertains to a loader of signatures or sheets with scale-shaped (imbricated) arrangement which are deposited onto the plane of a bookbindery feeder.
- According to the prior art, known loaders for signatures or sheets of this type have a limited use, since they present a difficulty when they are positioned on the side where bookbindery feeders have their separation and grasping mechanisms for signatures and sheets. This difficulty is due to the fact that signatures or sheets to be fed, arranged in a scaled fashion on the loader, must fall from a considerable height, thereby disarranging, to be deposited onto the feeder's plane, which creates operational problems. This is due to the fact that the loader must be positioned at such a height as not to interfere with the feeder's mechanisms. The feeder works properly without frequent stops when the stack of signatures or sheets on the withdrawal plane is low, since signatures or sheets are taken out of the lower part of the stack. A tall stack on the feeder weighs heavily upon the lower signature or sheet which is grasped by the feeder's mechanisms, thereby creating operational difficulties. Aim of the present invention is to solve the above mentioned problems, as will be detailed in the following description, which is merely exemplary and not limiting, and illustrated in the attached drawings, in which:
- FIGURE 1 represents a schematic view of the loader-feeder unit,
- FIGURES 2, 3, 4 represent the various stages of the mechanism object of the invention, connecting the loader to the feeder, and
- FIGURE 5 is a cross-section according to line V-V- of figure 1.
-
- In Figure 1, a loader 1 and a
feeder 2 are schematically represented. On the flat part of the loader 1 signatures or sheets 3 are arranged vertically and conveyed by conveyor belts 4. Upon contact with the elevator belts 5, for signatures or sheets 3 arrange themselves as scales until they come close to astacking basket 6 with the horizontal upper part 5' of belt 5. - In the basket, the signatures or sheets form a small stack 7 which is held in its correct position by means of
vertical shoulders 8 and 9 and supported by aretractable plane 10 made up of the shoulders 10' which can be seen in figure 5. One shoulder or bothshoulders 8 and 9 can be adjusted according to the size of the signatures or sheets 3. Theretractable plane 10 with its shoulders 10', at a minimum difference in height from 5', is connected by means of amember 11 to a preferablyrodless piston 12, which moves according toarrow 13 and causes the stack of signatures or sheets 7 to fall onto the plane 2' of thefeeder 2. Through this system a small stack 7 of signatures or sheets can be fed into thefeeder 2, and signatures or sheets are correctly positioned on the withdrawal plane 2' of thefeeder 2. At the same time the mechanisms of thefeeder 2, contained in theshaded area 14 of figures 1, 2, 3, and 4 on the loader's side 1 are bypassed. Thepiston 12 is equipped withsensors member 11 and by theprismatic member 17 having grooves 17' to allow adjustment when shoulders 10' move, as illustrated in figure 5. Such movement takes place in either direction along said grooves placing shoulders 10' in positions suitable to support signatures or sheets according to their size. - The
level sensor 18, which detects the lack of a stack or the presence of a stack of signatures or sheets which is too low, is fixed to the upper part of the loader 1. - The mechanism object of the invention, which comprises shoulders 10' and means suitable to move them, is fixed to the structure of the loader 1 through
rods - The operating sequence of said mechanism connecting loader and feeder is described hereinafter:
- the level sensor 18 (figure 2), upon detecting the lack of a stack or the
presence of a stack of signatures or
sheets 21 which is too low on the plane 2' of thefeeder 2, causes thepiston 12 connected to theretractable plane 10 with shoulders 10' to move in the direction of arrow 13'. Thesensor 16 stops the stroke ofpiston 12 in the position shown in figure 3 and in figure 1, at a short distance from plane 2'. After shoulders 10' have stopped in the position of figure 3 and figure 1, conveyor belts 4 and elevator belts 5 feed scale-arranged signatures or sheets 3 to form a small stack 7 that is well aligned in thestacking basket 6. -
- When the stack 7 is complete, for example after a time period measured by means of a timer, not shown in the figures, the shoulders 10' reach the retracted position shown in figure 4, intercepting the
position sensor 15, which adjusts the shoulders' 10' stroke according to the size of signatures or sheets 3. Thus the small stack 7 of signatures or sheets goes down correctly, without disarranging, onto the plane 2' of thefeeder 2 or onto the portion ofstack 21 lying on thefeeder 2. Shoulders 10' remain in the retracted position of figure 4 untillevel sensor 18 detects a lowering of the stack 7 of signatures or sheets, due to the fact that signatures or sheets are removed by the feeder from the lower part of stack 21 (figure 4). At this point, the loading sequence is resumed with shoulders 10' moving in the direction of arrow 13' (figure 2). - The movement of shoulders 10' can also be performed with equivalent means, such as belts, chains, motor-driven racks or racks driven by hydraulic pistons or similar means.
- The present invention can undergo practical changes without however departing from the scope of the present invention, as hereinafter claimed.
Claims (8)
- A loader of signatures or sheets with scale-shaped (imbricated) arrangement to be deposited onto the plane of a bookbindery feeder, characterized in that it comprises a retractable plane (10) onto which a small stack (7) of signatures or sheets (3) is deposited, which is then downloaded onto the plane (2') of the feeder (2) after the retractable plane (10) has moved back.
- A loader according to claim 1, characterized in that the retractable plane (10) lies at a minimum difference in height relative to the horizontal upper part (5') of a conveyor belt (5) of signatures or sheets (3) with scale-shaped arrangement, so that as a result the stack (7) on the retractable plane (10) is low.
- A loader according to any of the preceding claims, characterized in that the retractable plane (10) is located at a short distance from the plane (2') of the feeder (2) and offset from the mechanisms (14) of the feeder (2).
- A loader according to any of the preceding claims, characterized in that it comprises a level sensor (18) which detects the lack of a stack or the presence of a stack which is too low (21) on the plane (2') of the feeder (2) and causes the retractable plane (10) to move forward and a small stack (7) of signatures or sheets (3) to be loaded onto the retractable plane (10).
- A loader according to claim 4, characterized in that it comprises a means which interrupts the loading of said small stack (7) as soon as this has reached the set height and causes the retractable plane (10) to move back.
- A loader according to claim 5, characterized in that said means is a timer.
- A loader according to any of the preceding claims, characterized in that the movements of the retractable plane (10) are driven by driving means consisting essentially of a piston (12) equipped with sensors (16, 15) to check the end of stroke of the retractable plane (10) and to adjust the degree of movement of the retractable plane (10) according to the size of signatures or sheets (3).
- A loader according to any of the preceding claims, characterized in that the retractable plane (10) consists of various shoulders (10') which are caused to slide and positioned in grooves (17') on a support (17) integral with the A loader (1).
